FS: Fiber collimators.

[Kenom]

FS: Fiber collimators. 30W laser diode 805nm.

I've got some fiber collimators that work with a sma904/905 laser fiber optic cable. capable of up to 10W of power possibly more. Great for those Coherent FAP diodes.

Askin price is $35 shipped in con/us.

Pictured is a acrylic lens that does NOT come with it. This comes with a GLASS LENS.

Adjustable focus.

Is that a Aixiz lens I see on there? How about a picture of the connector on it.

 

[Kenom]

it is an aixiz. but it was only to take the picture. it will have a glass lens when shipped.

The thing that I see here is this:

Due to the small size of the lens and the relatively long focal length (for a fiber collimator) this will either loose a significant amount of light, or will only focus light coming from a fiber >100uM.

Light comes out of the fiber at around 70 degrees full angle. Do the geometry to figure out how much of the light would hit the lens.

 

[Kenom]

it's adjustable and has a fair amount of opening on the back of the lens. Since it will literally screw right down to the fiber, I'd say that it grabs a fair amount of said light. Works wonderfully for my 800um fiber that I've got here and my 30W diode.

I agree with you on the second link, however, the thorlabs ones are designed for either 65um or 125um fibers and do a horrible job with anything larger. I'm not trying to bash your product don't get me wrong, I think it is great to see a fiber collimator on the market for a reasonable price, but I think you should take into account the actual losses from large fibers.

 

[Kenom]

I've no doubt there are losses. Pretty much EVERY lens, mirror, or dichro is going to have losses. I saw that there were no affordable (<$125) fiber collimators and came up with a reasonable alternative. Given that there are none, I figured that the price for these and the capability is a great value. Not a lot of call for fiber collimators on this forum but with the introduction of fiber coupled lasers from Heruursciences as a result of his bulk purchase from boston laser, there are going to be those that will need them. I've got a 30W fiber coupled 805nm laser up for sale and that needs one too. ($199)

Thanks for your input though.
